Abstract: The magnetically separable composite Fe3O4 nanoparticles/attapulgite (MATP) is prepared by solvothermal method using Fe(NO3)3·9H2O as iron source and attapulgite (ATP) as starting material.The prepared MATP is characterized by XRD,FE-SEM,TEM,XPS,specific surface area/pore size analyzer and VSM.The results show that MATP is formed through the Fe3O4 nanoparticles with an average diameter of 11 nm dispersing quite uniformly over the surface of ATP.Meanwhile,MATP retains the nanorod and porous structure of clay,and has a specific surface area and average pore diameter of 180.98 m2·g-1 and 17.05 nm,respectively.Further study demonstrates that MATP is of superparamagnetism with a saturated magnetization of 13.44 emu·g-1,which helps composite clay materials to be separated from system as well as be recovered for recycle.
